The DBH 8306 radial shaft seal is a lip seal that blocks the passage of lubricant and prevents dust or water from entering equipment with a rotating shaft. It is press-fitted into the housing and runs on the shaft, with the right height for housings of limited section. It is a wear part: when oil leakage or contaminant ingress appears, it is replaced. MR Accesorios Industriales sells it as an official brand within its seal line.

This seal has the following dimensions: shaft diameter 57 mm, housing diameter 76 mm and height 9.00 mm. The design is Lz, a single lip with a spring that ensures continuous contact on the shaft. The designation 8306 identifies the exact size within the DBH line. Before mounting it, check that the housing and the shaft match these values; a difference of tenths can prevent the lip from seating properly or the part from fitting.

It is used in gearboxes, pumps, electric motors, transmission shafts and process equipment where oil or grease must be retained and dirt kept out. It is common in plant maintenance, workshops and machines operating with continuous rotation. It also appears in applications where axial space is limited and a compact seal is needed. If the equipment operates with heavy vibration or temperature, it is advisable to check the condition of the shaft before installing the new seal.

To select well, look at the condition of the shaft: it must not have grooves or burrs in the contact area, because the lip wears quickly. The housing must be clean and free of deformation. During mounting, lubricate the lip with the same grease or oil used in the equipment and tap evenly, without twisting the part. If the previous seal failed due to temperature, consider a different material. The designation 8306 and the Lz design guide you, but always confirm against the manufacturer's data sheet.

If you need an equivalent or a nearby size, send us the code 8306 together with the shaft, housing and height dimensions. It also helps if you tell us the equipment or the application. With that data we look for alternatives within the DBH line or from other brands we carry. You do not need to have the drawing: the code and the dimensions are enough to guide the search.
